[Sorry for the confused order of posts]
Hi,
The sensor datasheet just says "5V TTL (compatible)" ouput.
Thus it should be
LOW: <0.4V
HIGH: >2.4V
according TTL standard.
(You could easily find the values on your own: Just do an internet search for "TTL voltage levels")
Micro controller link -- **broken link removed**
This is not what I was asking for.
Please show a little effort on your own: Read the microcontroller (not the evaluation board) datasheet and find out V_IH and V_Imax. (as already meantioned in post#2)
Mind: The signal is no "digtal data" signal. It´s just a frequeny. --> you need to do a frequency measurement.

Hi,
I have tried it on my own only ,but everywhere i am seeing what is a TTL signal couldn't find how to interface read them with any MCU .
If you could explain me that would be really appreciated .
I won´t look for the datasheet, download it and search the document for "V_IH"...
It is your job, and if you want others do your job you should consider to pay for this.
But even for this you need to give the requested information: exact type of microcontroller.
It is a simple task you need to be able to do this on your own.
With almost every datasheet there is a section "electrical characteristics" ... there it should be easy to find "V_IH".
